Across
  1. 2. When matter changes from one state to another, depends on the movement of particles
  2. 6. The movement of thermal energy from a hotter substance to a cooler one
  3. 8. Phase of matter with no definite shape or volume and very separated particles moving at high speeds
  4. 10. Phase of matter with definite volume and particles that move and take the shape of their container
  5. 12. Solid to liquid
  6. 15. The uneven forces acting upon the surface of a liquid
  7. 17. When liquid molecules gain energy, break their attractions, and become a gas
  8. 18. When warm matter rises and cooler matter falls (Convection currents)
  9. 19. A liquid's resistance to flow
  10. 20. Phase of matter with definite shape and volume with particles that vibrate but do not move from place to place
Down
  1. 1. Liquid to solid
  2. 3. Solid to gas, when solid molecules move so fast that they overcome their attractions and become a gas
  3. 4. Direct contact between a heat source and matter
  4. 5. Anything that has mass and takes up space
  5. 7. When gas molecules lose energy and come together to form a liquid
  6. 9. When molecules can no longer move
  7. 11. Gas to solid (Frost)
  8. 13. The average kinetic energy of individual particles
  9. 14. An ionized gas
  10. 16. Heat travels through a vacuum
